Fragments from a meteor explosion over the Chelyabinsk region of Russia, approximately 920 miles to the east of Moscow, injured up to 500 1000 people, as windows were shattered, tiles fell, and the roof of factory collapsed.

The meteor has been estimated to have weighed around 10 tons and its explosion lit-up the sky with a massive flash of light, leaving an enormous plume of smoke.

According to the first news reports, Vadim Kolesnikov, a spokesperson for the Russian Interior Ministry, said 102 people had called emergency services for medical assistance following the incident—mostly for multiple injuries caused by broken glass and falling objects. This figure has now risen to over 520 1000, and includes dozens of children, and 2 that are currently in intensive care.

Footage of the explosion has been variously captured by cell phones, CCTV and on-board car cameras.
